By performing, on an original image having pixel values representing depths of positions on a textured surface of a target object, a conversion for making an element histogram of a steerable pyramid of the original image the same as or similar to an element histogram of a steerable pyramid of a reference image having pixel values representing depths of positions on a textured surface of a reference object, for each spatial frequency band and each orientation band, histogram modulated images are obtained, and the histogram modulated images obtained for the spatial frequency bands and orientation bands are synthesized to obtain an image corresponding to a modulated image having pixel values representing depths of positions on a textured surface of a modulated object.

A technique that automatically adjusts a motion given to a projection target using a perceptual model is provided. A motion vector generation apparatus includes a first parameter generation unit that generates a first parameter that is a parameter for scaling a motion vector based on a perceptual difference between a projection result reproduction image which is an image that is obtained when a projection target onto which a projection image obtained based on the motion vector has been projected is photographed and a warped image which is an image generated by distorting an image obtained when the projection target is photographed by a perceptual amount of motion perceived when the projection result reproduction image is viewed, and a motion vector reduction unit that scales the motion vector using the first parameter.

Provided is an image generation technology capable of suppressing unpleasant feelings caused by fluctuation in image quality caused by the viewer's viewpoint movement. The image generation technology includes an image generation unit configured to generate a pseudo viewpoint image Iand a pseudo viewpoint image I, by using disparity inducing edge Dhaving a phase difference &#x3c6;k from a viewpoint image I, where &#x3c6;k(1&#x2264;k&#x2264;K) is set as a real number satisfying 0&#x3c;&#x3c6;&#x3c; . . . &#x3c;&#x3c6;K&#x2264;&#x3c0;/2, an output image generation unit configured to generate an output image Out(1&#x2264;m&#x2264;2K&#x2212;1), from the pseudo viewpoint image I(1&#x2264;m&#x2264;2K+1), the viewpoint image I is set as a pseudo viewpoint image I, where the pseudo viewpoint images I, I(0&#x2264;k&#x2264;K) are arranged in a sequence of I, I, . . . , I, I(=I), I, . . . , and Iis set as I, I, . . . , I, I, I, . . . , I, and the output image Outand the output image Out(1&#x2264;m&#x2264;2K&#x2212;2) include a phase modulation component that is canceled out when synthesized and visually recognized.

Image generation apparatus, image generation method, and program

A video is superimposed on an object in order that the object will be perceived as if the object were given a motion. This video is a video including a luminance motion component corresponding to a motion given to the object.

Video presentation device, method thereof, and recording medium

To allow an observer wearing stereoscopic equipment to perceive a stereo image and an observer not wearing stereoscopic equipment to perceive a clear image. Based on an original image, an image containing phase-modulated components a and an image containing phase-modulated components b are generated. The image containing phase-modulated components a and the image containing phase-modulated components b are for one who sees the original image or a subject represented by the original image and the image containing phase-modulated components a with one eye and sees the original image or the subject and the image containing phase-modulated components b with the other eye to perceive a stereo image, and one who sees the original image or the subject, the image containing phase-modulated components a, and the image containing phase-modulated components b with the same eye(s) to perceive the original image. The phase-modulated components a are generated by shifting the phase of spatial frequency components of the original image by a first phase, and the phase-modulated components b are generated by shifting the phase of the spatial frequency components of the original image by a second phase being a different phase than the first phase.
